Cycle day 21 Progesterone levels

Maggie

Hey you guys, we have been TTC for about a year & half. I am currently on my 5th cycle of taking letrozole. I just got my progesterone level drawn & it was 41.9ng/ml. I have yet to get above 30 the past few months. This level was drawn when I was only 4DPO. I know that, that confirms I did ovulate, but is it concerning that it is so high? Or is it even high?
